SIIECIFIGATION' formingpart of Letters Patent No. 723,675, dated March24, 1903.

Application filed December 27,1901. senniro. 87.489. T mods-i r To allwhom it'nuty concern:

Be itknown that I, CHARLES SUMNER J OHM- sd N, a citizen of the UnitedStates,residing at B ownville', in the county of Piscataqnis and Stateof Maine, havei'nvented new and use fnlImprovementsin Pipe-Couplings,ofwhich the following is a specification.

This invention relates to a pipe or hose con ping.

' The object of the invention is to provile a coupling which may readilyattach two or more pipe or hose sections together, so as to make acontinuous line connection from thesource of supply to the outlet.

A further object is toprovidea coupling whereby the pipe or hose may beattached to the valve or other supply.

I A still further object is to provide means for capping or closing theend of the pipe.

Further objects, as wellas the' novel detailslof construction, willbeclearly described hereinafter and illustrated in the accorn panyingdrawings, in which- Figure 1 is a side elevation of two pipe-sectionssupplied with my improved coupling, the position of the lever beingillustrated just prior to applying or locking the coupling. Fig. 2 is atop plan view of the-same. Fig. 3

is a vertical longitudinal sectional view taken v through a pair ofnozzles and a coupling constructed in accordance with my invention.

v Fig. 4 is a transverse section on the line 4 4:

of Fig. 3.

Fig. 5 is a detailed view of the tightening-stirrup. Fig. 6 is a similarview of the intermediate ring into which the noz zles project. Fig. 7 isa detailed prospective view of one of the wedges. Fig. 8 is a sectionalview of the same. Fig. 9 is a side elevation of a T-joint constructed soas to be supplied with the coupling herein described.

Fig. 10' is an elbow-joint provided with lugs adapted to be engaged bycoupling. Fig. 11 is a similar view of a valve-joint constructed inaccordance with my improvement. Fig.- 12 is a side elevation of twopipe-sections connected together, showing the double-lever coupling.Fig. 13 is an end elevation of a clip to which the levers are adapted tobe socnre-d. Fig. 1 is a detail view of a tube which may be attached tothe twoends of the pipes to be coupled provided with a couplingconstrncied in accordance with my invention.

The reference-numerals 1' and 2 designate two nozzles representingthe'respective ends of two pipe sections, which are tapered slightly totheir respective ends and-fit in a ring 3, which is interposed betweenthe ends of the nozzles and overlaps the outer wall, whereby a tightjoint is made.

t On the nozzle 1 are formed two diametrically oppositely arranged lugsorprojections 4. and 5, having heads or shoulders (land 7 on theextremeends thereof.

A cylindrical sleeve 8 fits over-the ends of the nozzles 1 and 2 andover the ring 3-and carries on its respective endsoppositely-projectinglngs 9 and 10 of substantially the sameconstruction as those designated by the ref- Over the nozzle 2 isarranged a ri'ng 13,

which is fastened to the nozzle by'se'micylim drical wedges M, which arethreaded interiorly, so as to impinge against the nozzleswhen within thering.

A coupling-yoke (designated by the reference-numeral 15) is pivotallysecured. to the ring 13 by two parallel'inwardly-bent arm: 16 and 17,which project from said yoke, and

carries lugs" or projections 13 and19, which are adapted tovbe engagedby link-hars 19 and 20,which also engage the sleeve 8. Brackets or slots21 and 21 are formed in the ends of the yoke and in which are positionedremovable handles 22 and 2.3, arranged so thatby applying the pressureto the levers the yoke may be forced down upon the nozzle 2,

and thus draw the nozzles 1 and2 and ring 3 so close together that atight joint will be made. Onthe ends of the yoke are provided upturnedlips 24 and 25, which are adapted to be engaged by a strap, such asdesignated by the reference-numeral 26, as shown in Fig.-

4. This will keep the yoke in locked position when desired and retainthe pipe section coupled.

In Fig. 9 I have shown a T-joint 27, supplied with. lugs 4 and flanges4", which are adapted to be used in connecting pi pe-sections to a jointof this character.

diainetrical oppositely arranged openings 13 and 13 are arranged in theclipland at right angles with relatio'n'to the pivot-point. Theseopenings are for the purpose of receiving theends of the yoke 15, whichis connectedto the A lever 23.

I While 1 have specificallydescribed whatto me at this time appears tobe the very best means of accomplishing the desired'resnlt, I

will-have itnnderstood that I do not liniitmyself to the exact detailsof the construction shown, "but reserve the right to make such Y likechanges andalterations as may suggest themselves from time totimewithont'depsr'ting from the spirit of myinventi'on.

what I cl-(iiin as new, and desire to secure by Letters Patent,' isp 1;In a coupling the combination of a pair of-nozzleshaving taperede'ndsand an intermediatering into which thetapered ends pro je'ct,ahsle'e vle fitting over the ring in. ends of the nozzles, aConnection-hem enone-of the nozzles a nd he 1slee ve,end pivoted latchcarried bythe 0th rnozzle and eo'nnected'tgo' the sleeve, saidlat hbeing adapted tobe con'-' nected so as todraw'the'nozzles together.
